I put in BcM which is on the floor panel on the pasture side in 2005 Mustang still one headlight is out 1 stays on when you turn the car off 2 backlights don't work and break light and directionals can you please help

The headlights will turn on the low beams but they will they won't turn on at all like the low beams will not turn on I can get my marker lights and everything else on but just my low beams will not work my high beams I can I can push the switch forward inside the cabin and it'll those will turn on but not the low beams
